a look at the front lines of identification technology. >> reporter: the most common means of identification are photo i.d. cards, and passwords. but the use of biometric data is making identification easier and more secure. some smartphones recognize the owner's fingerprint. last month japanese electronics maker hitachi unveiled this security gate. just a touch of the hand is enough to verify your identity. and you can walk through without even stopping. the system quickly recognizes people based on vein patterns in their fingers. it's a highly accurate means of identification, but past systems needed too much time to process data. this one can verify 70 people in just one minute.

a 3-d scanner pinpoints the location of the hand. at the same time infrared lights scans veins in the hand. the system works regardless of the position and shape of the hand. >> translator: the system recognizes people based on their fingers so it's extremely accurate. we believe it could be used at the gates at train stations. >> reporter: japan is a leader in the field of vein recognition, as well as other forms of biometric identification. last year the u.s. national institute of standards and technology named japanese company nec as the developer of the world's most outstanding facial recognition technology. the company developed a system that compares scanned data with more than 3 million facial images per second. it's 99.7% accurate.

this is a picture of me seven years ago. this photo data has already been registered in this computer. if a face matches a registered image, an identification number appears. now let's see how it works. oh, it recognizes me right away. the system recognizes faces, despite changes over time, and different facial expressions. this means it can match people with older images such as passport photos. people who have not been registered in the system are identified as unknown right on the spot. >> translator: the major selling point is the system's flexibility. it can recognize faces even if the angles change. people don't always look straight ahead. when they turn their heads, smile, or frown, their facial expressions change. >> reporter: the system not only pinpoints the location and angle of the face.

it also recognizes detailed facial features such as the shape of the nose or mouth. the technology is already being used by immigration officials in hong kong and shenzhen southern china. at concert venues it quickly verifies tens of thousands of visitors registered to attend an event. the developers are working on making it possible to link scanned faces to personal data. they also plan to use facial recognition to make shopping easier. with these new advancements one day we may never have to worry about forgetting our passwords. mikiko suzuki, nhk world, tokyo. the people who run japan's shinkansen railway service are looking to raise the bar. they've seen their bullet train
